POURING-STOPPER FOR LIQUID-CONTAINERS.

' Specification of Letters Patent.

Patented Aug. 26, 1919.

Application filed April 5, 1915. Serial No. 19,228.

To all whom it may concern:

Be it known that we, BUY D. lVirrriNe and ALoNzo A. WIII'IING, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pouring-Stoppers for Liquid-Containert; of which the following is a specification.

This invention relates to stoppers for botties and other liquid containers, and its obj ect is to provide such a stopper with a pouring outlet which is so arranged that the liquid contents of the bottle may be decanted through the same without dripping on or smearing the stopper or any part of the bottle.

The invention also has for its object to provide the stopper with an air vent which allows air to enter the bottle and thus induces a free flow from the outlet.

The herein stated objects are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing in which Figure 1 is an elevation of a fragment of a bottle and the stopper thereof; Fig. 2 is a. similar View showing the opposite side of the bottle, and Fig. 3 is a central vertical section of the stopper.

Referring specifically to the drawing, 5 denotes an ordinary bottle or other liquid container having a neck 6 in the mouth of which is seated, and held by friction, a stopper 7 of cork, wood, rubber or any other suitable material. The outer end of the stopper body has an enlargement to form a head 8, which latter does not enter the bottle mouth but is on the outside thereof when the stopper is in place.

In the enlarged outer portion or head 8 of the stopper is a transverse duct 9, and the body of the stopper has, two longitudinal ducts 10 j and 11, respectively, leading from its inner end to the duct 9 and opening thercinto. In the head 8 is also a small air inlet port 12 opening through the side thereof, and leading to and communicating with the duct 9. This port may be located to open into the end of the duct 9 opposite the outlet end of the latter, or it may open .into said duct on the side. The drawing shows the first mentioned arrangement, and the side of the head therefore has diametrically opposite openings, one of which is the outlet end of the duct 9 and the other the port 12. The duct 10 is designed to carry the liquid to the duct 9 and it therefore opens into the latter ad acent to its outlet end. The duct 11 is for the purpose of admittitng air to the bottle when its contents are bcmg poured out and it opens into the duct 9 adjacent to the port 12.

It will be noted that the diameter of the duct 9 is considerably greater than that of the air port 12, and the ducts 10 and 11 have the same diameter. The diameter of the duct 9 is slightly greater (about onethird) than the diameter of the ducts 10 and 11. The greater diameter of the duct 9 is for the purpose of accommodating the volume of liquid which may pass thercinto from the ducts 10 and 11, and for preventing interruption of the flow by the liquid becoming air bound in the duct 9. Should any liquid enter the duct 11 it will flow into the duct 9 and continue on its course to the outlet without becoming air bound and its flow being interrupted, this being due to the fact that the air admitted through the small port 12 is not sufficient to offset the weight of the liquid passing through the duct 11. The liquid is also prevented from passing out through the port 12 and causing a smeared stopper or bottle.

The diameter of the head 8 is such that the outlet end of the duct 9 is flush with the outer surface of the bottle neck 6 and not inside the same, which is for the purpose of inducing a free flow from said duct without the liquid touching the bottle, its neck or the edge of the head, thus avoiding the dripping on or smearing of the stopper or any part of the bottle while the liquid is being poured out, or when the flow is discontinued. After decanting, the bottle being tipped upright again, any liquid remaining in the duct 9 is immediately drawn back into the bottle by the partial vacuum in the latter, thereby preventing smearing of the head or the bottle, and maintaining the bottle in a clean, dry and sanitary condition.

The port 12 and the outlet end of the duct 9 will be provided with suitable closures to be applied when the bottle is not in use. A

cap 13 is shown dotted in Fig. 1 fitting over the head 8. Any other closure may be employed.

We elaimz- A bottle stopper comprising a single unit composed of a plug having a body portion which is enlarged at its outer end to form an integral head, the body portion fitting removably in the'neck of the bottle, and the head being on the outside thereof and having a smooth, unobstructed side surface to seat a cap, said head being provided with a transverse outlet duet opening through its side, and the body portionhavinglongitudinal pourlng and air duets extending from its 10 inner endand eoinmunicatlng with the afore- Copies of thispatent may be obtained for five'centseach, by addressing the Commissioner of Patents,

air inlet. port being less than that? of the out-' let duct.

In testlmony whereof we aliix our slgnatures'.
